So when I render maya fur with out nhair driving it I get normal render times in mental ray (15min or so). However, when I attach maya nhair to drive and style the fur it makes the render times go crazy, like an 1hr an 15min. And I'm not sure what causes that and how I can reduce it. I'm using pretty basic render settings. No final gather or GI, depth map shadows with fur self shadowing enabled. Also this is just for rendering a single frame using mental ray. I created a cache, and baked all the attribute maps as well.
Also wasn't sure if this should be posted in dynamics or rendering thread since I don't know the real issue here.
Thanks
